Welcome to Healing Well! Sorry you're having problems. GERD has a tendency to get worse over time, unfortunately. Hopefully you'll be able to get it under control.
I haven't had problems with PPI side effects, but I know they occur.
Have you tried Zantac? You can get a script for a generic version, and take up to 300mg if you need extra strength. It tends to only work for a while, and then the body seems to adjust to it, and it's not as effective. Still, it might help you through this bump in the road.
There are a wide variety of PPIs, and some people have side effects with some, and not others. I'm sure others will be by to share their experience and information.
Glad you've joined the forum!
